Why can clay be shaped?
1. The earliest and most direct modeling method of pottery is hand-making, which is the oldest and the embryonic form of the origin and development of pottery.

2. Stamping: Pottery is made by stamping, which is mainly used to make tableware and some decorative utensils. Put the prepared clay into the model to be made, pressurize and inject compressed air to form the required pottery.

3. Slurry pouring: This method is mainly used to produce a large number of ceramics. Put the mixed mud glaze into a gypsum mold to form a certain shape in the mold, and then discharge the excess mud glaze, so that the remaining materials in the mold can be made into needed pottery.
